Empty Sella Turcica

Sella turcica is a saddle shaped depression in the sphenoid bone of the skull. The base of the saddle is called hypophyseal fossa which holds the pituitary gland. Sella turcica means Turkish saddle.

 

Empty sella syndrome is a disorder involving sella turcica, a bony structure in the base4 of skull which holds pituitary gland. Persons with empty sella turcica will have defect in the tissue barrier that normally keeps the cerebrospinal fluid around the brain separate from sella turcica. Due to this the cerebrospinal fluid increases pressure on the pituitary gland and the walls of the sella turcica. The sella turcica may enlarge and the pituitary gland may shrink.

It is mainly common in middle aged women who are overweight and who have high blood pressure. It commonly occurs after pituitary surgery, radiation therapy or infarction of a pituitary tumor.
